This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

9 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Domain Expires Soon

      Domain expires in 18 days

      What to do: Renew domain registration before expiration

  4. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

CeSYS targets travel agencies and tour operators, providing SaaS solutions including search engines, web design, sales systems, and marketing tools. The business model revolves around subscription packages with tiered offerings. Partnerships with major travel industry players like Amadeus and Delta Reisen enhance credibility and market reach. The company has a medium size and a history dating back to 2008, indicating stability and experience. The website content and structure support lead generation and customer engagement through demos, newsletters, and training events. The presence of sister sites in Czech Republic and Hungary suggests regional expansion and localization strategies.

Security posture

The website employs HTTPS with good SSL configuration and uses cookie consent banners compliant with GDPR. Tracking technologies include Google Analytics and Facebook Pixel, with user consent mechanisms. However, explicit security policies, incident response contacts, and vulnerability disclosure mechanisms are absent. Security headers such as Content-Security-Policy and X-Frame-Options are not explicitly detected, representing an area for improvement. No exposed sensitive data or vulnerable libraries were found. Overall, the security posture is solid but could benefit from formalized policies and enhanced header configurations.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information on the website.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Consider creating a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Expand contact information to include direct company emails and phone numbers for better user trust and support.
  5. Regularly audit third-party scripts and tracking technologies to ensure compliance with evolving privacy regulations.

Technical notes

Notes

The website uses a custom CMS tailored for travel agencies with a modern tech stack including jQuery, Bootstrap, and various JavaScript libraries for UI and analytics. Hosting is supported by regional CDNs ensuring fast content delivery. The site is mobile optimized and SEO friendly with proper meta tags and Open Graph data. Performance is good with lazy loading images and asynchronous script loading. Some technical debt may exist due to legacy libraries like jQuery, but overall the infrastructure supports scalability and user experience. Opportunities exist to modernize frameworks and enhance accessibility features.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
